The Turbo Duo is still and I beleive always will be the system with
the best pack-in software.

Gate Of Thunder, Ys Book I & II, Bonk's Adventure, Bonk's Revenge,
Bomberman AND Ninja Spirit(one of the many arcade ports that now look
more impressive than ever).

Even if they'd stuck with Dungeon Explorer instead of Ninja Spirit,
no other console's pack-ins come close. I do think they made they
right decision swapping DE for NS, even though I'm such a big RPG fan.

Although I think it's only fair to compare launch packages, even if
you include any of the lucrative modern console bundles, I still
think the Turbo Duo's far and away the best.
